I have and am using a Panasonic HDC-HS9 and am really happy with it. it has a 60Gb hard drive and uses SDHC cards. It records HD video into the AVCHD format and (with the proper editor, I am using Pinnacle 12)it produces a HD image (which is Broadcast quality on my TV) and full surround stereo due to the built in 5 channel mics which seem to to be very effective.
